Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If wooden stakes and strings are used to mark building foundations, then the method is simple and inexpensive, but it is time-consuming and prone to misalignment

Engineering Contradiction:

Improvealignment precisionVSAvoidtime consumption

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the mechanical manual staking method with a laser-based measurement system. The laser measuring device projects laser beams that can be detected by sensors, enabling automated and more precise alignment without requiring manual adjustment of wooden stakes and strings, thus reducing time consumption while improving alignment precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The laser measuring device performs self-alignment through its laser projection and detection mechanisms. The device automatically establishes reference lines and planes without requiring continuous manual intervention, allowing the system to serve itself in maintaining precise alignment throughout the staking process.

Inventive Principle:

Principle #25Self-service

2Reliability

If wooden stakes and strings are used to mark building foundations, then the equipment is simple and inexpensive, but it creates waste and is risky

Engineering Contradiction:

Improvemeasurement reliabilityVSAvoidmaterial waste

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent eliminates the need for disposable wooden stakes by using a reusable laser measuring device. The laser system provides reliable measurements without the physical degradation and misalignment issues associated with wooden stakes, thereby improving measurement reliability while eliminating material waste.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Instead of discarding wooden stakes after use, the patent employs a reusable laser measuring device that can be used multiple times without degradation. This approach recovers the utility of the measurement tool across multiple projects, eliminating the waste associated with disposable staking materials.

Inventive Principle:

Principle #34Discarding and recovering

3Measurement precision

If global positioning satellite-based systems are used, then measurement precision is improved, but the cost increases significantly

Engineering Contradiction:

Improvepositioning precisionVSAvoidsystem cost

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent uses a laser-based measurement system that replaces expensive satellite-based positioning systems. The laser measuring device, with its projection and detection mechanisms, provides sufficient precision for foundation staking at a fraction of the cost of GPS or satellite-based systems, making high-precision measurement more accessible.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs a relatively simple and inexpensive laser measuring device compared to satellite-based systems. While the laser device requires periodic calibration and maintenance, its lower initial cost and simplicity make it an economically viable alternative to expensive satellite-based positioning systems for routine construction staking tasks.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
